Tire Sizing?

[BlueCollarTahoe]

got a 2004 tahoe, gathering information for future use. Want to change the tires to All Terrain but im curious how big can i go without doing any sort of modification around the wheels? i believe the wheels are 16 on there, please let me know if im wrong. If its indeed 16's, can you go bigger without trimming the space around or lifting or can only stay 16?

Stock wheels, 285/75/16's with only a minimal crank of the torsion bars to level the front with the back. Some say 295's might fit, but 285's rubbed on mine unless I cranked mine all the way up.
